Abstract
Disclosed is a fire-extinguishing agent spray device including a spray container for storing a fire-extinguishing agent, and including an inwardly convex container bottom surface, and a siphon tube in the spray container, and including a lower end adjacent to the container bottom surface and having an inclination angle with respect to a reference line based on a center of an inner surface of the container bottom surface.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A fire-extinguishing agent spray device comprising:
a spray container for storing a fire-extinguishing agent, and comprising an inwardly convex container bottom surface; and a siphon tube in the spray container, and comprising a lower end adjacent to the container bottom surface and having an inclination angle with respect to a reference line based on a center of an inner surface of the container bottom surface.
2 . The fire-extinguishing agent spray device as claimed in claim 1 , further comprising a discharge valve coupled to an upper end of the spray container.
3 . The fire-extinguishing agent spray device as claimed in claim 2 , wherein the siphon tube comprises an upper end connected to the discharge valve.
4 . The fire-extinguishing agent spray device as claimed in claim 3 , wherein the siphon tube comprises a hollow tube.
5 . The fire-extinguishing agent spray device as claimed in claim 4 , wherein the reference line is based on an inner top point of the container bottom surface.
6 . The fire-extinguishing agent spray device as claimed in claim 5 , wherein the reference line is a horizontal line passing through the inner top point of the container bottom surface.
7 . The fire-extinguishing agent spray device as claimed in claim 6 , wherein the inclination angle of the lower end of the siphon tube is about 0 degrees or more.
8 . The fire-extinguishing agent spray device as claimed in claim 7 , wherein a distance (h) from the lower end of the siphon tube to the inner top point of the container bottom surface is calculated as follows:
h

wherein r t represents an inner radius of the siphon tube, and wherein ρ represents a pitch of a thread for assembling the siphon tube to the discharge valve.
9 . The fire-extinguishing agent spray device as claimed in claim 4 , wherein the inclination angle of the lower end of the siphon tube is equal to or less than an inclination angle of the container bottom surface.
10 . The fire-extinguishing agent spray device as claimed in claim 9 , wherein the inclination angle of the lower end of the siphon tube is about 10 degrees or less.
11 . The fire-extinguishing agent spray device as claimed in claim 10 , wherein a distance (h) from the lower end of the siphon tube to an inner top point of the container bottom surface is calculated as follows:

wherein r t represents an inner radius of the siphon tube, wherein p represents a pitch of a thread for assembling the siphon tube to the discharge valve, and wherein θ represents the inclination angle of the lower end of the siphon tube with respect to the reference line based on the center of the inner surface of the container bottom surface.
12 . A fire-extinguishing agent spray device comprising:
a spray container for storing a fire-extinguishing agent and comprising an outwardly convex container bottom surface; and a siphon tube in the spray container, and comprising a lower end adjacent to the container bottom surface and having an inclination angle with respect to a reference line based on a center of an inner surface of the container bottom surface.
13 . The fire-extinguishing agent spray device as claimed in claim 12 , further comprising a discharge valve coupled to an upper end of the spray container.
14 . The fire-extinguishing agent spray device as claimed in claim 13 , wherein the siphon tube comprises an upper end connected to the discharge valve.
15 . The fire-extinguishing agent spray device as claimed in claim 14 , wherein the siphon tube comprises a hollow tube.
16 . The fire-extinguishing agent spray device as claimed in claim 15 , wherein the reference line is based on an inner bottom point of the container bottom surface.
17 . The fire-extinguishing agent spray device as claimed in claim 16 , wherein the reference line is a horizontal line passing through the inner bottom point of the container bottom surface.
18 . The fire-extinguishing agent spray device as claimed in claim 17 , wherein the inclination angle of the lower end of the siphon tube is about 0 degrees or more.
19 . The fire-extinguishing agent spray device as claimed in claim 18 , wherein a distance (h) from the lower end of the siphon tube to the inner bottom point of the container bottom surface is calculated as follows:
